The Admin port is a physical ethernet port directly connected to the controller's management plane. It provides a dedicated connection to a secure management VLAN. The controller can use the Admin port to interact with RADIUS, SNMP,and Extreme Management Center servers.
The Static IP Address specifies the address assigned by the administrator.
In the Mask field, type the appropriate subnet mask for the IP address (typically, 255.255.255.0).
The MTU value specifies the Maximum Transmission Unit or maximum packet size for this topology. The fixed value is 1500 bytes for physical topologies. The maximum MTU can be increased to 1800 bytes by enabling Jumbo Frames support (for more information, see Setting Up the Data Ports).
The Gateway field specifies the IP address of the default gateway for the Admin port.
The Static IPv6 Address field specifies the address assigned by the administrator.
The Static IPv6 Gateway field specifies the IP address of the default gateway for the Admin port.
The Prefix Length field specifies the length of the IPv6 prefix. Maximum is 64 bits.
The MTU value specifies the Maximum Transmission Unit or maximum packet size for this topology. The fixed value is 1500 bytes for physical topologies. The maximum MTU can be increased to 1800 bytes by enabling Jumbo Frames support (for more information, see Setting Up the Data Ports).
The Dynamic IP Address lists the current auto-generated IPv6 addresses assigned to the Admin port.
Note
IPv6 supports multiple addresses on the same port including auto-generated addresses such as a link-local address, or an address created by combining the Router Advertisement prefix with the interface ID. Auto-generated addresses generated via the Router Advertisement prefix are dynamic and their availability depends on the existence of the prefix (or lack of) in the Router Advertisement.Or, click Cancel to close the Edit Topology dialog without saving any changes to the port configuration.
